Amoebiasis among institutionalized psychiatric patients in Taiwan.

Although information on amoebiasis among institutionalized psychiatric patients is available, reports on the relationship between behaviour and this infection are not abundant. From July 1995 to June 1996, stool and blood samples were collected from 565 patients in three psychiatric hospitals of North Taiwan. Stool samples were examined using the direct smear and formalin-ethyl acetate sedimentation techniques as well as ProSpecT Entamoeba histolytica Microplate Assay kit. Blood samples were examined by the Amebiasis Serology Microwell ELISA kit. Among these patients, 14 (2.5%) harboured one or two species of intestinal parasites. There were 6 (1.1%) E. histolytica/E. dispar cyst passers: 5 positive in stool ELISA test and 2 with antibodies against E. histolytica. Among demographic factors, type of psychiatric disorder and disability, only a significant sexual difference in seropositivity of E. histolytica was observed. These findings indicate that the infected patients acquired the infections before they entered the hospitals.

Efficacy of saccharomyces boulardii with antibiotics in acute amoebiasis.

AIM: To compare the efficacy of antibiotics therapy alone with antibiotics and saccharomyces boulardii in treatment of acute amebiasis. METHODS: In a double blind, random clinical trial on patients with acute intestinal amoebiasis, 57 adult patients with acute amoebiasis, diagnosed with clinical manifestations (acute mucous bloody diarrhea) and amebic trophozoites engulfing RBCs found in stool were enrolled in the study. Regimen 1 included metronidazole (750 mg Tid) and iodoquinol (630 mg Tid) for 10 days. Regimen 2 contained capsules of lyophilized saccharomyces boulardii (250 mg Tid) orally in addition to regimen 1. Patients were re-examined at two and four weeks after the treatment, and stool examination was performed at the end of week 4. Student's t-test, chi(2) and McNemar's tests were used for statistical analysis. RESULTS: Three patients refused to participate. The other 54 patients were randomized to receive either regimen 1 or regimen 2 (Groups 1 and 2 respectively, each with 27 patients). The two groups were similar regarding their age, sex and clinical manifestations. In Group 1, diarrhea lasted 48.0+/-18.5 hours and in Group 2, 12.0+/-3.7 hours (P<0.0001). In Group 1, the durations of fever and abdominal pain were 24.0+/-8.8 and 24.0+/-7.3 hours and in Group 2 they were 12.0+/-5.3 and 12.0+/-3.2 hours, respectively (P<0.001). Duration of headache was similar in both groups. At week 4, amebic cysts were detected in 5 cases (18.5 %) of Group 1 but in none of the Group 2 (P<0.02). CONCLUSION: Adding saccharomyces boulardii to antibiotics in the treatment of acute amebiasis seems to decrease the duration of clinical symptoms and cyst passage.

Antiamoebic activity of 3,3'-fluro-4,4'-di-(pyrrolidine-2-ylidene amino)-diphenyl (liroldine), against experimentally infected intestinal and hepatic amoebiasis.

HL 707, Liroldine, a novel synthetic compound, was found effective against both extraintestinal and intestinal amoebiasis in animal models. Its activity against hepatic infection in golden hamsters is comparable with that of different derivatives of nitroimidazoles used for human treatment. Against intestinal amoebiasis in Wistar rats, the activity was superior to nitroimidazoles and chloroquine. Paramomycin was comparable and diloxanide furoate was marginally superior. The comparative in vitro and in vivo studies with standard marketed drugs and Liroldine indicate an excellent profile of the compound against experimental amoebiasis. LD50 of Liroldine determined in mice is 910 mg/kg x 1, po and 940 mg/kg x 1 ip).

Amebiasis in the newborn.

Infestation with Entamoeba histolytica is especially common in areas with low socioeconomic status. Extra intestinal invasive involvement is more frequent in young children with significant mortality. This disease is rarely reported in the newborns. This 19-day-old newborn who was infected with orally given surgar solution is presented. He was successfully treated with omidazole.

Intestinal parasites in homosexual men.

A study on the prevalence of intestinal parasites in a group of homosexual men, attending a sexually-transmitted diseases clinic in Glasgow, was undertaken. Of 118 men examined over an eight-month period, four, one of whom had symptoms of dysentery, were found to be infected with Entamoeba histolytica. Cysts of Iodamoeba buetschlii were also found in the stool of one of these men. A further two patients had giardiasis, and 11 men had enterobiasis. The importance of an awareness of these conditions is discussed.

Evaluation of the indirect haemagglutination test in the diagnosis of amoebiasis.

The IHA test was evaluated in the diagnosis of amoebiasis. Axenically-grown E. histolytica was used as an antigen. A total of 427 sera from symptomatic (intestinal and extra-intestinal) amoebiasis patients. asymptomatic carriers, patients with parasitic intestinal infections other than E. histolytica, and healthy controls were tested. From 288 symptomatic cases of amoebiasis, 232 (80.6 per cent) gave positive reactions. In 93 asymptomatic cases of amoebiasis, 55 (59.1 percent) were seropositive. In testing of sera from 16 subjects with parasitic intestinal infections other than E. histolytica, a low-level positive IHA titres occurred in 2 (12.5 per cent). The test was also positive with a low titre in 3 (10.0 per cent) of the 30 subjects of the healthy control group. The results indicate that the IHA test is of value in the confirmation of intestinal and extra-intestinal amoebic infections especially in cases where the parasite is difficult to demonstrate.
